Nine students named winners in Living Worlds Space Art Contest

Nine students in kindergarten through fifth grade are first, second or third place winners in Notre Dame’s first Living Worlds Space Art Contest in which students are asked to imagine and depict the unusual forms of life that might inhabit other planets. In addition to the artwork, entrants also include written descriptions of their creature, describing how it has adapted to conditions on its planet.

Over 1,000 students from ten states submitted entries to the contest which allows students to explore evolution, adaptation and the discovery of planets around other stars. Entries are divided into classroom categories of grades K-1, 2-3 and 3-5. Prizes have been awarded for first through third places in each grade range.

International Society for Optics and Photonics highlights iLocater in recent publication

spectrograph_design

The iLocater instrument being developed by Justin R. Crepp, the Freimann Assistant Professor of Physics at Notre Dame, has been featured by the SPIE, the International Society for Optics and Photonics, in a paper describing the detection of planets around other stars. The article by Crepp, entitled “Renaissance of the Doppler technique for exoplanet studies,” was published online on Sept. 10 by SPIE and describes how new hardware will enable breakthroughs in instrumentation performance that could lead to the discovery of nearby worlds that might resemble the Earth.

Justin Crepp presents "Earth-like Worlds Orbiting other Suns"

Earth Like Worlds

Notre Dame physics professor Justin Crepp discusses expolanets and how to find them. There are 100 billion stars in the Milky Way galaxy. Do these stars have orbiting planets? If so, are they similar to the Earth? Do they have life? In this talk, Prof. Crepp will address these questions by explaining how astrophysicists detect and study planets located outside the solar system.…

Notre Dame celebrates 150 years of science

Rev

The University of Notre Dame’s College of Science will celebrate 150 years of science at Notre Dame beginning this month through September 2015. The college will host numerous events throughout the year in collaboration with the local community and national sponsors.

The Center for History will offer a year-long exhibit, “From Astrophysics to Zebrafish: 150 Years of Science at Notre Dame.” Focusing on Notre Dame’s history of scientific research and education, the exhibit includes artifacts of early scientific lab equipment, fossils and photographs of legendary Notre Dame scientists and their discoveries. The exhibit is open to the public through Aug. 2, 2015. Admission is charged.

NASA has named University of Notre Dame astrophysicist Justin Crepp as a member of the Transiting Exoplanet Survey Satellite (TESS) science team. A space mission coordinated through MIT, Harvard, and NASA’s Goddard Space Flight Center, TESS will discover thousands of exoplanets in orbit around the brightest stars in the sky.

Crepp, The Freimann Assistant Professor of Physics, was selected to be on the science team based on his team’s expertise with adaptive optics and their ability to use the Large Binocular Telescope, the world’s premier diffraction-limited facility, to acquire follow up observations for intriguing planetary signals that TESS will detect.

Physicists confirm first planet discovered in a quadruple star system

The first extrasolar planet in a quadruple star system has been discovered

Justin Crepp, Freimann Assistant Professor of physics at the University of Notre Dame, provided the high-contrast imaging observations that confirmed the first extrasolar planet discovered in a quadruple star system. He is a co-author on a paper about the discovery, “Planet Hunters: A Transiting Circumbinary Planet in a Quadruple Star System,” recently posted to the open-access arXiv.org, and submitted for publication to The Astrophysical Journal.

Crepp’s images revealed that the system involved two sets of binary stars. The planet was first noticed by volunteer citizen scientists studying publicly available Kepler data as part of the Planet Hunters citizen science project.
